    Massive filaments fuel the growth of galaxies and supermassive black holes

    Based on direct observations researchers have discovered massive filaments between galaxies in a proto-cluster, extending over more than 1 million parsecs and providing the fuel for intense formation of stars and the growth of super massive black holes within the proto-cluster. (1) A filament fit for space: Silk is proven to thrive in outer space […]

  • Harsh sounds…

    Harsh sounds…

    Neuroscientists have analyzed how people react when they listen to a range of different sounds, the aim being to establish the extent to which repetitive sound frequencies are considered unpleasant. Their results showed that the conventional sound-processing circuit is activated but that the cortical and sub-cortical areas involved in the processing of salience and aversion […]

  • Mountains!

    Mountains!

    Life on Earth is amazingly diverse, and exhibits striking geographical global patterns in biodiversity. A pair of companion papers reveal that mountain regions — especially those in the tropics — are hotspots of extraordinary and baffling richness. Although mountain regions cover only 25% of Earth’s land area, they are home to more than 85% of […]

    Self-reference. Beauty.

    When something pleases us visually – whether it’s a fine piece of artwork, a beautiful feat of architecture, or an untouched natural landscape – new research demonstrates there is a pattern of activity in what’s known as the default mode network (DMN). The DMN is a large-scale system of interacting regions in the brain that […]

    Organoids. Brain waves. Death…

    Some years ago, two hundred and fifty miles over Alysson Muotri’s head, a thousand tiny spheres of brain cells were sailing through space. The clusters, called brain organoids, had been grown a few weeks earlier in the biologist’s lab here at the University of California, San Diego. He and his colleagues altered human skin cells […]
